The medical name for this condition is epicondylitis. The condition is characterised by pain and tenderness on the outside of the elbow and is the result of inflammation in the TENDON that attaches the muscles which extend the elbow to the HUMERUS bone. Epicondylitis can be the result of playing a lot of tennis or other racquet sports, gardening, ‘do it yourself’ work, or any activity that constantly pulls the tendon at its point of attachment. Lifting heavy objects aggravates the condition. Treatment is resting the arm, ANALGESICS and/or NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS). Sometimes ULTRASOUND therapy may promote healing, but persistent severe pain may result in a recommendation of a local injection of CORTICOSTEROIDS. Rarely, surgery may be advised to release the tendon.
